Dracal USB-PTH200-CAL

Product Highlights

PTH200: All-in-one USB temperature sensor, with relative humidity and atmospheric pressure sensors

The PTH200 is designed for environmental temperature, relative humidity and atmospheric pressure (barometric) data acquisition. Its core digital sensors chips are factory-calibrated, linearized and temperature-compensated and can detect very small variations.

With its factory calibrated, linearized and temperature compensated digital sensor chip, it is field interchangeable and very small variations in temperature and humidity can be acquired using a standard USB port.

The compact probe eases integration, even in space-constrained locations, and the internal particle filter provides protection against dust, soot, and other contaminants.
